Unusually moist tropical air will continue to flow into the area this afternoon and overnight. Storms will develop to the north and west of the region this afternoon then expand into the region overnight. The ground is saturated and any rainfall will rapidly convert to runoff. These storms will be capable of intense rainfall rates of 2 to 4 inches per hour. These storms may become anchored in an east to west band with storms moving north north colliding with the boundary and probably intensifying rain rates. Where the boundary sets up is still difficult to pinpoint but probably in the zone between the Interstate 10 corridor and College Station and Huntsville. Rainfall totals of 2 to 4 inches should be widespread over the watch area with localized amounts of 7 to 10 inches. Street flooding may become widespread in the watch area and travel overnight should be reconsidered. Rivers and streams across the watch area may quickly flood with the heavy rainfall. Stay informed on the weather overnight.

The rains should gradually move out of the region Saturday afternoon. More storms may form Sunday and then another system arrives Monday and Tuesday bringing more rainfall.

* Streets... bayous... streams and rivers will likely have the greatest impacts from the heavy rainfall. Motorists and persons with outdoor activities should stay ado not drive your vehicle into areas where the water covers the roadway. The water depth may be too great to allow your car to cross safely. Vehicles caught in rising water should be abandoned quickly. If your vehicle stalls... abandon it and seek higher ground immediately. Rapidly rising water may engulf your vehicle and its occupants and sweep them away. Move to higher ground.Breast of the latest forecasts and have contingency plans in place when the heavy rain arrives late this afternoon and tonight.
